en CB01 OFFICIAL. Didier Travolta is a 40-year-old disco music fan who has no job, lives with his mother, and has a son he hasn't seen for a while. The mother of his son refuses to send him their son for the holidays unless he can offer him a real vacation, not just going to bars of the French port city of Le Havre. Penniless, the only way he can see his son is by winning a dance contest organized by his friend Jackson, with the prize of a vacation to Australia for two.
